Iraq's Ambassador to the United States since April of last year, Samir Shakir Mahmoud al-Sumaydi, is no stranger to Capitol Hill, where one side of the test of wills between Congress and President Bush is playing out.
The Iraqi diplomat used an address to a room full of congressional staffers to lay out what he sees as the stakes in Iraq, for Iraqis, the Middle East, the United States and the world.
Iraq he says is at the epicenter of a momumental confrontation between two universes and two sets of ideology the outcome of which will have long-lasting impact.
"It is the central line of battle. That is why it is very important what happens in Iraq. It is very important who wins in Iraq, important not only for Iraqis important to every individual in this country. There is a big cost attached to this struggle, but there is likely to be a much bigger cost if it is lost. We have to think of that," he said.
The ambassador's view parallels that of President Bush who describes Iraq as the central battle against al-Qaida, along with Islamist extremism.
Between now and September, the administration and Congress will receive two key reports on progress, or the lack of it, in Iraq and the new joint Iraqi/U.S. military strategy, reports that could prove decisive.
Against a backdrop of continuing low public approval numbers for President Bush, and Iraq-related politics in the 2008 U.S. presidential contest, Democratic leaders plan to use legislation to transition U.S. forces away from a combat role, and remove the authority lawmakers gave him in 2002 for military action.
Although he prevailed in forcing Democrats to remove troop withdrawal language from Iraq funding legislation, cracks in the president's support are seen in statements by Republican leaders that continuing bad news will require the president to change course.
In a VOA interview, North Carolina Republican Sue Myrick says Americans support the cause of democracy in Iraq, but have a limit to their patience as they wait for some sign of progress by Iraq's government in achieving political and economic benchmarks.
"It is their country, they have to be running it, they have to be training their military, they have to stop the sectarian violence, they have to do those things. We are there as backup support and that is what General Petraeus is doing, he is providing the training and backup support. Whether it is going to work or not, I can't tell you. I can just tell you that patience runs very thin and there is a cutoff point for this relative to how much more support we give to them (Iraqis)," she said.
Other voices heard on Capitol Hill include Lieutenant General Martin Dempsey, former Commanding General of the Multinational Security Transition Command in Iraq.
In describing what he called key capability gaps in Iraq's military forces, he said Iraq's leaders are fully aware they cannot rely on the indefinite presence of a sizable U.S. force.
"Everyone understands that there will be a declining U.S. presence at some point, to include the Iraqis understand that and they are beginning to ask me how much bigger should they grow in order to offset the declining U.S. presence, and the answer to that question is the pace at which we eventually decline," he said.
In separate remarks to Congress recently, President Bush's new coordinator for Iraq and Afghanistan, Lieutenant General Douglas Lute, had this observation on the need for Iraqis to seize the moment for political reconciliation:
"We are giving them a golden opportunity that they must seize to make progress on the political front. I don't think there is any doubt in the mind of any Iraqi politician that this is an opportunity they have to seize," he said.
This remark by Congressman Roscoe Bartlett provided another example of the signals the administration and U.S. military leaders are receiving from Republicans. "Our constituents are very uneasy with terms like stick it out and stay the course. They have no idea what that means. If that means we are going to be there 50 years from now, like we are in South Korea, they have got no stomach for that sir," he said.
In testimony to the House Foreign Affairs Committee this past week, Former Secretary of State Lawrence Eagleburger, who was a member of the independent Iraq Study Group, said a U.S. withdrawal under what he called adverse circumstances would be a serious mistake:
